Pull request overview

Adds a new daily agentic workflow that queries Grafana tracing data to evaluate the repository’s OpenTelemetry (OTel) instrumentation and files a single actionable GitHub issue for the highest-impact improvement.

Changes:

• Introduces a new markdown-based gh-aw workflow definition for a “Daily Grafana OTel Instrumentation Advisor”.
• Adds the compiled/pinned .lock.yml workflow produced by gh aw compile for scheduled execution in GitHub Actions.

Hey @mnkiefer 👋 — great addition! A daily workflow that mines Grafana OTel traces and surfaces actionable GitHub issues sounds like a fantastic observability improvement for the project.

One thing that would help get this across the finish line:

• Add tests — the new workflow (daily-grafana-otel-instrumentation-advisor.lock.yml, 1,493 lines) doesn't appear to have any associated test coverage. Even a lightweight integration/smoke test or a workflow validation step (e.g., using actionlint or a test workflow that exercises the main job logic) would go a long way toward maintainability. Also, per the contributing guidelines, make sure to run make agent-finish before marking this ready (build, test, recompile, fmt, lint).

If you'd like a hand, you can assign this prompt to your coding agent:

For the new GitHub Actions workflow at .github/workflows/daily-grafana-otel-instrumentation-advisor.lock.yml, do the following:
1. Run `actionlint` (or equivalent YAML linter) on the workflow file and fix any issues reported.
2. Add a companion test workflow (e.g., `.github/workflows/test-daily-grafana-otel-instrumentation-advisor.yml`) that exercises the core job steps using mock/stub inputs so CI can validate the logic without requiring live Grafana credentials.
3. Run `make agent-finish` and fix any build, lint, or formatting issues it surfaces.

Done. Ran make fmt and make lint — both pass. Commit 0e629df applies the formatting fixes to the lock files.
